Abstract 15637: Elective Admissions for Congestive Heart Failure Are Associated With Higher Inpatient Mortality and Hospital Costs, a Nationwide Analysis Using the National Inpatient Database of 2013
Background: Congestive heart failure (CHF) is one of the most common causes of hospital admissions and readmissions in the United States. The majority of patients with CHF who visit the emergency department end up being admitted to the hospital. Limited data is available about the differences between emergent or urgent admissions and patients admitted after being referred by their primary doctors.
Methods: This is a retrospective cohort study using the 2013 National Inpatient Sample (NIS) of adult patients hospitalized with CHF as the admitting diagnosis. We aim to determine if an elective admission affects inpatient mortality and total hospital costs. Non-elective admission was defined as any emergency, urgent, and trauma admission. We adjusted our results for age, gender, Charlson Comorbidity Index and hospital bed size.
Results: We identified a total of 876, 050 patients admitted for CHF during 2013; we divided them into two groups (elective vs non-elective admission). 59,075 patients had an elective admission to the hospital. The mean age was 72.5 years for both groups; 45.8% were female in the elective group and 49.3% in the non-elective group. Our analysis showed that there was 46% more chance of inpatient mortality if the admission was elective (adjusted OR 1.46, p<0.00). Similarly, elective admissions cost US$ 4860 more when compared with non-elective admissions (US$ 15,975 vs US$11,116, p<0.00).
Conclusion: Elective admissions in CHF patients are associated with a higher probability of inpatient hospital deaths and higher hospital costs.
